Trace element composition of atmospheric particles collected at a high altitude site on the Eastern Black Sea coast of Turkey was investigated to understand atmospheric transport of pollutants to this semi-closed basin. Aerosol samples were collected at a timber-storage area, which is operated by the General Directorate of Forestry. The site is situated at a rural area and is approximately 50 km to the Black Sea coast and 200 km to the Georgia border of Turkey. Coarse (PM2.5-10) and fine (PM2.5) aerosol samples were collected between 2011 and 2013 using a "stacked filter unit". Collected samples were shipped to the Middle East Technical University in Ankara, where Na, Mg, Al, Si, S, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Ba, Pb were measured by Energy dispersive x-ray fluorescence technique (EDXRF). Comparison of measured concentrations of elements with corresponding data generated at other parts of Turkey demonstrated that concentrations of pollution derived elements are higher at Eastern Black Sea than their corresponding concentrations measured at other parts of Turkey, which is attributed to frequent transport of pollutants from north wind sector. Positive matric factorization revealed four factors including three anthropogenic and a crustal factor. Southeastern parts of Turkey, Georgia and Black Sea coast of Ukraine were identified as source regions affecting composition of particles at our site, using trajectory statistics, namely "potential source contribution function" (PSCF).
在土耳其黑海东海岸的一个高海拔地点收集的大气颗粒物中的微量元素组成进行了研究，以了解污染物向这个半封闭盆地的大气传输情况。气溶胶样品是在一个木材储存区收集的，该储存区由林业局总局运营。该地点位于一个农村地区，距离黑海海岸约 50 公里，距离土耳其与格鲁吉亚的边境约 200 公里。在 2011 年至 2013 年期间，使用“堆叠式滤器单元”收集了粗颗粒（PM2.5-10）和细颗粒（PM2.5）气溶胶样品。收集的样品被运往安卡拉的中东技术大学，在那里使用能量色散 X 射线荧光技术（EDXRF）测量了 Na、Mg、Al、Si、S、K、Ca、Ti、V、Cr、Mn、Fe、Ni、Cu、Zn、As、Ba、Pb 等元素的浓度。将测量的元素浓度与土耳其其他地区生成的相应数据进行比较表明，黑海东部的污染衍生元素浓度高于土耳其其他地区测量的相应浓度，这归因于来自北风区的污染物频繁传输。正矩阵因子分析揭示了包括三个人为因素和一个地壳因素在内的四个因素。使用轨迹统计，即“潜在源贡献函数”（PSCF），确定了影响我们站点颗粒组成的来源区域，包括土耳其东南部、格鲁吉亚和乌克兰黑海海岸。
